Method of driving an electron emission device

Abstract

Provided is a method for driving an electron emission device that reduces the required withstand voltage of an integrated circuit constituting a scan driver, which reduces both the manufacturing costs of an electron emission device and the likelihood of noise in the scan driver, as well as preventing back emission. Scan signals are applied to scan electrode lines during a scan period and an offset period, which is a non-scan period. Display data signals are applied to data electrode lines during a first data period, when a difference between a voltage of the display data signal and a voltage of the scan signal is greater than or equal to an emission start voltage; and during a second data period, when the voltage difference is less than the emission start voltage.
